you can try also same method as for MST10 based devices: viewtopic.php?f=53&t=5015

I want to have a try
Can you Explain ?
2."Apache server" what is this for ?
3."Test Applet" whehe is it ?is it will show up with USB insert?


Instructions:
1. Set up a development environment on your PC and TV (read wiki how to do this).
2. Extract htdocs.zip to your Apache htdocs folder. Edit widgetlist.xml and change 192.168.1.2 to IP address of your Apache server.
3. Unzip usb_card_updated.zip to the root directory of FAT-formatted USB stick.
4. Turn on a TV and wait until it completely boots.
5. Insert USB stick to TV, install and run the "Test Applet" widget on TV
6. Press "enter" on remote, the widget would do its dark things.
7. Exit widget and run "Web Browser". It should display a black screen for >10 seconds and then the browser would start. If browser starts immediately (this happens sometimes) - rerun browser again.
I've added a 10-second delay on the hack start to see that it works.

After this - you'll get a shell access via telnet on port 23 on TV IP address, and a FTP access to its filesystem.
Shell access allows you to execute commands and see their output. This is not a complete telnet daemon as we don't have devpts driver on TV. So do not try to execute interactive commands - you'll see their output, but would be unable to enter text. Code is taken from here: http://www.andreadrian.de/remsh/index.html with minor modifications (added a delay after popen). Later I'll replace this shell with something better.

With usb plug method, i saw 2 log files on my usb disk. One of them seems to be an sqlite database.

Nothing happens with this method. When i try to install "Test widget" bd stuck at 0% and i must to power-off.

Tried "SamyGO.py patch ./B-FIRHT7WWC_1012.5" and it ends with:
SpoilerShow
"CRC Validation passed

Traceback (most recent call last):
File "G:\SAMSUNG\SamyGO.py", line 1289, in <module>
SamyGO( sys.argv[2] )
File "G:\SAMSUNG\SamyGO.py", line 1239, in SamyGO
firmware,md5digg,decfile,encmode = Decryptor( in_dir )
TypeError: 'NoneType' object is not iterable"
For usb hotplug method i need patched firmware, and i haven`t. On server 1011 version isn`t patched.
I don`t have any ideas, and i saw there are many ppl with same problem. Maybe you can manage to help us all and you`ll be happy with our thanks and donations:)

and what's in your webservers log files? normally widgets get downloaded in any case, on installation the smarthub makes some "security checks" and maybe rejects the installation

Nothing strange on my web server logs.
In access.log:
"192.168.1.125 - - [11/Feb/2013:14:25:35 +0200] "GET /widgetlist.xml HTTP/1.1" 200 311
192.168.1.125 - - [11/Feb/2013:14:25:36 +0200] "GET /Widget/Test2_0.100_America_20121115.zip HTTP/1.1" 200 3411"
And in error.log nothing related to widget request.
When i try to sync develop account with my server, download progress barr is stucked at 0%. Strange.
I suppose is not a problem with my web server because when i try to install samygo widget, the widget its downloaded and when it try to install error appear.

Can I try anything else or just wait for a new method for my device?

@rainie, sorry, nothing `till now. I have tried everything i found on this forum. We hope that maybe SammyGo will be compatible with our devices in the future. It will be safest, fastest and most easy solution for new gen of bd-players.
